Neon Design System Tokens, Color Palette & Cursor SKILL.md

Aesthetic Archetype — Serverless Pitch-Black & Luminous Cyber-Mint Postgres: Pitch-black #000000 canvas with #242628 / #303236 dark structural borders, 56px tight -0.04em Inter display headings, and #34D59A / #00E599 luminous cyber-mint accents. Use these deterministic CSS tokens and arbitrary Tailwind values in Cursor or Claude Code to replicate Neon’s visual precision without generic AI purple-gradient slop.

## 1. Aesthetic Direction & Vibe
- **Archetype**: **Serverless Pitch-Black & Luminous Cyber-Mint Postgres**
- **Semantic Vibe Tags**: `dark`, `postgres`, `serverless`, `database`, `mint`, `neon-green`, `pitch-black`, `neon`
- **Core Signature**: Pitch-black #000000 canvas with #242628 / #303236 dark structural borders, 56px tight -0.04em Inter display headings, and #34D59A / #00E599 luminous cyber-mint accents.
- **Atmosphere & Contrast Strategy**: Built on a dark-mode foundation (`#000000` canvas -> `#131415` elevated surfaces) anchored by `#242628` structural borders, `Inter` display typography, and `#34D59A` primary accents.

### Motion & Transition Curves
- **Easing Curves (`transition-timing-function`)**: `cubic-bezier(0.4, 0, 0.2, 1)` (90x)
- **Transition Durations**: `0.2s` (88x), `0.15s` (2x)
- **Named Motion Tokens**: `--ease-in: cubic-bezier(.4, 0, 1, 1)`, `--ease-out: cubic-bezier(0, 0, .2, 1)`, `--ease-in-out: cubic-bezier(.4, 0, .2, 1)`, `--default-transition-duration: .15s`, `--default-transition-timing-function: cubic-bezier(.4, 0, .2, 1)`, `--rt-transition-show-delay: .15s`

## 5. Anti-Patterns (Strictly Forbidden)

- **NEVER substitute generic uncalibrated gray backgrounds for Neon’s exact `#000000` canvas and `#131415` surface pairing.**
- **NEVER replace `Inter` display typography or ignore its signature scale (`56px / -0.04em (w400)`).**
- **NEVER use thick opaque borders that clash with `#242628` (`1px solid #242628`).**
- **NEVER deviate from the signature button geometry (`9999px (Pill)`) or introduce off-brand saturated gradients.**
- **NEVER use default browser monospace when rendering code or telemetry**—always pair with `JetBrains Mono`.
